Application April 3, 1958, Serial No. 726,133

4 Claims. (Cl. 20-65) This invention relates to new and useful improvements in weather strips for swinging double doors and more particularly to weather strips which permit either double door to be freely opened or closed.

A principal object of the present invention is to provide a weather strip for swinging double doors to prevent rain, snow, wind or cold air from entering a building through the gap between the meeting edges of the swinging double doors.

Another object of the present invention is to provide a weather strip for swinging double doors which permits either door to be freely opened and closed.

Another object of the present invention is to provide a weather strip for swinging double doors which is effective even when the door panels are misalined when closed and which reduces the amount of friction or resistance to a minimum in opening and closing the doors.

Other objects of the present invention will be pointed a 6 out in part and become apparent in part in the following specification and claims.

Referring to the drawings in which similar characters of reference indicate corresponding parts in all the figures:

Figure 16 is a schematic plan view showing one operative position of the doors before resetting.

Referring to Figures 1 through 8 wherein is illustrated one form of the new and improved weather strip for swinging double doors.

Reference character 5 designates a door frame upon which a pair of swinging double doors 6 and 7 are carried by hinges 8 and 9, respectively. Asusual, the doors swing inward in the direction of the arrows A, B. Ordinarily, door checks (not shown) are employed for closing the doors.

A filler block 15, preferably as thick as a weather strip 10, may be secured to either door 6 or 7 but is illustrated as fixed to door 7. A weather strip 10 is pivotally mounted to filler block 15 by means of hinges 11, 12, 13. Screws 14 secure said hinges to filler block 15. Screws 16 secure said hinges to weather strip 10.

Weather strip 10 extends the full length of doors 6 and 7 and overlaps the crevice 17 which normally exists between swinging doors, such as 6 and 7.

A cam 20 is adjustably secured to door frame 5. Weather strip 10 engages to slide against the cam surface of cam 20 whenever door 7 is swung from closed to open position and back to closed position. Cam 20 holds weather strip 10 against door 6. Door 6 is free to swing from closed to open position and back to closed position without disturbing weather strip 10 as is clearly illustrated in Figure 4.

Door 7 may be swung from closed to open position and back to closed'position without hinderance from door 6, as is clearly illustrated in Figures 5 and 6. Figure 5 showing door 7 swinging in the direction of arrow C with weather strip 10 ridingcam 20 to a position against both doors as illustrated in Figure 3.

Referring to Figures 7 and 8 door 7 carrying weather strip 10 may be provided with a hand guard rail 21 fixed to door 7 to allow door 7 to be pushed and thereby swung on hinges 9. The guard rail 21 will prevent pushing door 7 through contact with weather strip 10. Normally, doors 6 and 7 are provided with hand rails 23, 24 respectively.

Referring to Figures 9 through 14 wherein is illustrated a modified form of the new and improved weather strip illustrated in Figures 1 through 6.

Reference character 5A designates the reverse side of door frame 5 and may be deemed to be the inside of the building. Door frame 5 would therefore designate the outside entrance to the building. Obviously, the desig nations may be reversed.

Door frame SA has pivotally or swingably mounted upon it by means of hinges 8A, 9A a pair of swinging double doors 6A, 7A which are the reverse side of doors 6, 7. As usual, the doors 6A, 7A, swing inwardly in the direction of the arrows A, B.

A filler block 15A preferably as thick as weather strip 10A is fixed to door 7A. A Weather strip 10A is pivotally mounted to filler block 15A by means of hinges 11A, 12A, 13A. Screws 14A secure said hinges to filler block 15A. Screws 16A secure said hinges to weather strip 10A.

Weather strip 10A extends the full length of doors 6A, 7A and overlies the crevice 17 which normally exists between swinging doors 6A, 7A.

Weather strip 10A is provided with an extension 1013. A lever 30, fabricated from spring steel, is secured to door 6A by means of screws 31 and extends across the face or width of extension 10B. Lever 30 holds weather strip 10 against both doors 6A, 7A covering crevice 17. See Figure 10. Lever 30 is equivalent in mechanical function to cam 20.

A stop 32 consisting of a right angled bracket may be fixed to weather strip 10A so as to prevent the pivoting portion of weather strip A from pivoting more than ninety degrees.

When door 6A is swung from closed position Figure 10 to open position, Figures 13 and 14 in the direction of arrow A, the edge of door 6A pivots weather strip 10A around hinges 11A, 12A, 13A and lever 39 moves away from the edge of weather strip 10A, simultaneously. As door 6A moves to closed position Figures 13, 14 in the direction of arrow C, lever 30 engages the edge of Weather strip 10A, to pivot weather strip MA on hinges 11A, 12A, 13A, to cause the weather strip to lie flat across the crevice 17 in contact with doors 6A, 7A, in the same mechanical manner as cam 20.

When door 7A is swung from closed position, Figure 10, to open position, in the direction of arrow B, Figure 12, weather strip 10A will lie against the outside of lever 30, Figure 16. It is then necessary to swing door 6A from closed to open position to cause lever 39 to pivot weather strip 10A to open position, Figure 14, so that lever 3t} liesbeyond the edge of weather strip 10A. Then, see Figure 13, lever 30 will engage the edge of weather strip 10A to pivot it closed.

Figure 15 illustrates a modified form of flat weather strip 103 provided with a resilient insert 10C. Weather strips 10, NA may be fabricated from fiat strips of aluminum or rust proofed steel.

The modified form illustrated in Figures 9 through 14 and 16 is used in place of the form illustrated in Figures 1 through 6.

Having shown and described preferred embodiments of the present invention, by way of example, it should be realized that structural changes could be made and other examples given without departing from either the spirit or scope of this invention.
